' To all wkom it may] concern:

and useful Improvements in Dynamo- Mounting, of which the following is a full, clear, and exact description, suchas w ll ens able others skilled in the art to which it appertains to make and use the same. I This invention relates to the mountin of electrical machinery, and, with regar to certain more specific features, to the mount- 'ing of a dynamo adapted to be driven from a car axle.

One of the objects of the present invention is to provide a dynamo mounting of simple, cheap and compact structure and efficient action.

Another object is toprovide a mounting of the above type in which'the parts are so disposed as to hang low upon a car truck without interfering with parts of the car or truck and tively.

Another object is to provide a dynamo yet perform their functions effecmounting in which the parts are readily accessible and yet the dynamo is securely and safely supported.

Other objects will be in part obvious and in part pointed out hereinafter. The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the following claims.

In the drawings, in which is illustrated one of various possible embodiments of the invention, Figure 1 is a plan view of part of a steel car-truck with a dynamo mounted thereon in accordance with the invention; Fig. 2 is a longitudinal elevation, partly in section, of the apparatus shown in Fig. 1; and Fig. 3 is an end elevation of the same.

Similar reference characters refer to similar parts throughout the several. views of the drawings. g

Referring now to the drawings, there is illustrated at 1 a portion of a steel cartruck of any suitable or approved construction, provided with the necessary mecha- "Dism for securing thereto the axle 2 carrying the wheels 3, 4 adapted to run on the rails 5, 6. The rotation of the wheels 3, 4 on the rails 5, 6 is utilized to drive a dynamo 7 as by the pulley 8 on the axle 2, the pulley 9 on the dynamo shaft 10, and the interconnecting belt 11.

It may here be noted that the term dynamo is used throughout this specification and the following claims in what is believed to be its accurate technical meaning, namely, as designating a piece of electrical machinery which is employed either to generate electric current or to transform the same into mechanical. energy. In the present instance, the illustration relates more particularly to a machine for generating electric current. A beltdrive is illustrated, because it has been found satisfactory in actual service, although it will be obvious that many features of the present invention would be equally applicable to dynamos provided with other forms of power transmitting mechanism. The electrical power generv ated by the dynamo is conducted as by the wires 12 to suitable regulating devices, and thence to translating devices located preferably on or in the car.

Coming now to the embodiment of the mounting illustrated in the drawings, the dynamo? is provided with lugs 13, 14, at its opposite ends engaging the upper horizontal shafts 15 and 16, to which are pivotally secured the substantially vertical and preferably parallel plates 17 18, thus making the belt tension independent of the direction of rotation of the dynamo. It is to be understood that the term plate is used throughout as comprehending a rigid member extending, not necessarily uninterruptedly, over a material surface rather than along a line. .These plates are adapted as by connections at 19, 20 with the lower horizontal shafts 21, 22 for pivotal movement with respect to opposite portions of the horizontal. bed 23. The upper and lower shafts are preferably prevented from turning with the plates 17, 18, so that all wear comes on' of the depending yoke or stirrup 26 mounted at 27, 27 on the truck frame 1. The other end of the bed 23 is likewise adjustably secured to the truck frame 1 by means of the depending members 28, the transverse bar 29, the bolt 30 and the bolt and slot connections at 31. The several slots at 24:, 31 are arcuate in shape, and are struck about the axis of the vertical bolt 30 as a center, there-- by providing for the adjustment as a unit of the bed 23, the dynamo 7 and the associatedv parts about the axis of bolt30 as a vertical pivot; by this means the dynamo shaft may be readily and accurately brought into parallelism with the car axle 2. In addition to the securing and adjusting means provided in the bolts at 2 1, 31, there are illustrated at 32 two bolts with suitable lockfrom the drawings, this arrangement 'provides a compact and easily accessible mounting in which the dynamo is kept low and out .of the way of the deep center sills used in modern steel car construction, and a maximum clearance is insured above and below the apparatus, as no part of the device projects above or below the dynamo itself.

The operation of the illustrated embodiment of the invention is as follows: The

. justing bolts 32 are then made fast and the ed, the plates 17 and 18 are preferably sub-v swinging plates 17, 18, by keeping the upper and lowershafts 15, 16, 21 and 22 at all times in a constant angular relation, preferably parallel, without any adjustment what-' ever, preserve the alinement of the driving and driven pulleys. After alinin the axle and the dynamo shaft, the desire belt tension is obtained by means of the adjustable cup 35, and the parts are so proportioned that when the belt tension has been adjuststantially Vertical, so that vertical shocks to the truck will not affect the tension of the driving belt. If at any time some part should break and allow the dynamo to fall, the disastrous consequences that too often result from the dynamo falling on the track are avoided, for the dynamo simply drops a few inches to the supporting bed 23 and is cific features of the invention herein deg scribed and all statements of the scope of the invention, which, as'a matter of language, might be said to fall therebetween.
